Limited knowledge on fine-scale cropland fragmentation in China • A new synthetic cropland fragmentation index (CFI) was developed. • Counties with high and …
Fragmentation of landholdings is commonly regarded as a major obstacle to agricultural production growth in China. This study analyses the factors contributing to land fragmentation, and uses - and village-level data from 11 villages in Jiangxi Province to test these factors empirically.Our analysis shows that land fragmentation in …
This research utilizes microeconomic data from 2019 to 2020, encompassing 8609 samples from China's rural areas, to analyze the impact of farmland fragmentation …
Most of China's old-growth forests persist in small, isolated fragments from which many native species have disappeared, on land unsuitable for human utilisation. Fragmentation throughout China is likely to have major consequences on biodiversity conservation, but few studies have considered these large-scale processes at the national level.
Cultivated land fragmentation (CLF) has severely affected China's agricultural production efficiency, large-scale operations, agricultural modernization, and food security. Exploring the spatiotemporal evolution patterns and driving forces of CLF is crucial for agricultural modernization. However, t …
By presenting concrete evidence, the study highlights the issue of cropland fragmentation in China and discusses the potential obstacles it creates for the country's …

1. Introduction. Cultivated land fragmentation (CLF) refers to that driven by natural and human factors, cultivated land is divided into fragmented plots of different sizes with a discrete or disorderly land use pattern, which renders the large-scaled operation of agricultural production difficult (Ntihinyurwa and de Vries, 2020, Abubakari et al., 2016).

1. Introduction. The increasingly prominent problem of cultivated land fragmentation (CLF) in China is detrimental to large-scale land management, restricting the enhancement of land use intensity (Yang et al., 2018; Ye et al., 2021) and hindering agricultural modernization and industrialization.While most studies have focused on the …
2.1 Causes and governance of land fragmentation in China. Cropland fragmentation is not a new phenomenon in China. It is closely related to the extreme scarcity of land and irreversible population growth. However, today's intense discussion about land fragmentation dates back to the late 1970s or early 1980s, when the …

Zhang et al. [8] reported that the grinding scale of black tea was a key parameter affecting the extractable contents of phytochemicals as well as functional properties. Mechanical fragmentation can reduce the particle size of biomass material and destroy the tissue matrix and cell walls [10]. The disintegration of cell structures may ...

This study investigated the failure mechanism associated with the rock mass structure and the dynamic fragmentation process of blocky rocks of the 2018 Daanshan rockslide that occurred on 11 August, 2018. It was found that the initially collapsed rock of this rockslide was partitioned along the unconformity and strata interfaces. We analyzed …
Context The study of habitat fragmentation is fraught with definitional and conceptual challenges. Specifically, a multi-scale perspective is needed to address apparent disagreements between landscape- and patch-based studies that have caused significant uncertainty concerning fragmentation's effects. Objectives Here we test the …
